Hello, I'm trying to understand the use of a HEMT as a power amplifier. I want to design a driver for a power amplifier and so I need to deliver enough current to charge the gate capacitance. I wanted to know if there is any other current I should take into consideration.
For instance, the...
Hi, guys.
These days I was doing some HEMT chips testing, here is my test condition:
Set drain voltage to 48v const;
Sweep gate voltage from -6v to -1v, 251 steps totally(0.02v a step), sweep speed is 1000Hz.
Source was set to floating.(which was connected to power supply's sense low).
I caught...
